supported by a carrying wheel and as shown the outer end of the arm is 33, rotatably mounted upon the arm. If desired, as when cutting the first swath of grain about the edge of a field bounded by a-fence,the cradle 30 may be moved to an inoperative position by swinging the arm 31 forward toward the side of the frame 15, being provided for receiving and supporting the outer end of the arm when in this posi-' tion. When the cradle 30 is in use, backward movement of thejarrn 31 is limited by a brace rod 179, extending from the forward partof the frame'15 to the outer end. of the arm, sections, as 180, 181, of the brace rod 179 being flexible, as by being formed of chain, to permit the arm 31 to yield forwardly. The cradle 30, in shape, preferably takes the form of a tapered trough having open ends, and being longitudinally disposed with respect to the direction of move meut of the machine, the larger end of the trough being at the rear. As shown, the cradle comprises a: plurality of curved ribs 34, united intermediate their ends by longitudina-lly inclined stays 35, 36, 37, one of such stays, as 35, being preferably located upon the median line of the cradle and the other stays, as 36, 37, being located upon either side of the stay 35 adjacent the foot of the trough. A smooth floor for. the cradle may be provided by covering the ribs 34 and stays 35, 36, 37, Wit-h a curved plate 38.

The body. of the cradle just described is mounted upon"the arm 31 to swing in a vertical plane by'means of brackets 39, 40, 41, rigidly secured to the stays-35, 36, 37, re spectively, and rotatably receiving the arm 31. To limit the swinging of the cradle, a pin 42 (Fig. 2), fixed in the arm 31, traverses a slot 43 in one of the brackets, as 39. A spring 44, 'coiled about the arm 31, is secured at one end, as at 45, in the arm 31 and bears upon the bracket 39 at the other end to yieldingly maintain the cradle 30, when empty, ina substantially horizontal position against the stop 42.

Means are provided for compressing the bundles of grain contained in the cradle 30 and for retaining them in position in the cradle as it swings downwardly about the arm 31 from the horizontal position illustrated by full lines in Fig. 2 of the drawings, and for releasing the compressed bundles when the cradle reaches the discharging position illustrated by dotted lines in Fig.

As shown, a pair of curved arms 46, 47, are mounted ateach side of the cradle. to over the contents of the cradle. The arms 46, 47, of each pair are secured to a shaft 48, rotatably mounted in bearing blocks, as 49, 49, and 50, 50, secured to the brackets 40. 41, provided for supporting the cradle. For

gaging the cam rollers 52 to a hooked bracket 144 the ends of the; cam

swing ards 60* its outer end a cam-engaging roller 52, is

the shafts 48.

53, 54, are pivotally 31, as at 141, for enswing the arms 46, 47, over the contents ofv the cradle 30 as it turns about the arm 31 to the discharging position. A spring 55 reacts between the crank-arms 51 for yieldingly maintaining the arms 46, 47, in the open position illustrated by full lines in Figs. 1 and 2 of the drawings. As shown, each of the cam-fin; gers 53, 54, is tapered, and they act upon the cam rollers 52 during the cradle 30 about the arm 31 in one direction only. When the cradle has turned to the discharging position the cam rollers 52 pass fin ers 53, 54, and the arms 46, 47, are opened by the spring ,55 reacting between the crank-arms 51. During the return movement of the cradle to the horizontal receiving position, the rollers 52 traverse the spaces 142 behind the cam fingers 53, 54, the fingers being turned about the pivots 141, against the effort of springs 143, secured at one end to crank-arms 143 carried by the pivots 141, and at-the other to studs 143 mounted on the arm 31, to permit the cam rollers to pass. Preferably the shafts 48 carrying the arms 46, 47, are inclined to the'axis of the cradle 30, whereby the bundles of grain contained therein are more firmly compressed by the arms 46, 46, mounted on the shafts adjacent one end than by the arms 47, 47, thus forming the bundles into a shock of tapered form having a broad base before depositing them upon the ground.

For transferring the bundles from the binder mechanism 28 to the cradle mounted upon each of Movable cam fingers mounted. upon the arms 30, and for turning the bundles end to end comprising a pair of of grain horizontal plane at the top of a post 59,

havinga bifurcated head 66, each arm of the head being further divided to provide bearings, as 64, 65, for each of the fingers of the fork.

For supporting the post 59 and other operative parts, the machine is provided with a deck 61 covering the frame 15. An upright sleeve 60, having standards 60 at its foot, secured to the deck 61, provides a bearing for the post- 59. As most clearly shown in Figs. 2 and 7 of the drawings, the post 59 extends downwardly between the standthrough the deck, and is held against vertical movement in the sleeve 60, by the bifurcated head 66 and by a collar 66 carried by the post at opposite ends of the sleeve.

The fingers 57, 58, of the fork 56 are unequal length, and each has an over-1 turned outer end 62, 63, these overturned cause of the unequal length of the fingers,

. nected with each of the i the gear 71. Any

This'rod is operatively confingers 57, 58, by means of crank-arms 68, 69, mounted on the fingersbetween the bearings 64, 65, and havlIlig a pin and slot engagement with the s 0t. 1

For communicating. power from they ro tating axle 23 6f the machine to the cutter blade 27 the binder mechanism 28, the

fork'56, and to mechanism for controlling the swinging of the cradle 30 upon the arm 31, a; driving gear 71,,located upon the axle members 16, 17, of the frame 15, is provided. This gear is prefer ably loosely mounted upon the axle 23, but is adapted to be rotated by the axle, when desired, and when the machine is driven in a forward direction, as shown, b means, of a clutch member 7 3, having inclined clutch teeth 72, which is splined to' the axle and is movable into and out'of enga ement with a complementary formed face of the .hub of means conveniently .ac-

During the operation of the machine grain mowed by the reaping platform 26 is con-- tinuously delivered to the binder mechanism 29 by moons of the elevating apron comprisiug the sgqrocket chains 29. When a suili cieut queutity of groin has accumulated upon the binder mechanism to depress the fingers 15.50, the clutch 149 is operated by contact of the iuppet bar 153, curried by the qfiugers 150, with the stud 154, to"rotatobly connect the sprocket Wheel 127 with the coun't'er'sl1uft 80, and cause the binder mechanism, comprising the shaft 12% and hr'xotting mechunism including the twineca'rrying arm 1249, to be operatedby the sprocket choiu126. li henthe shaft 124: has 6 turned through a complete; revolution, the

to bemomenturily Withdrawn from beneath the head of the pin 121 against the effort The in 121 to rotetably connect the tubular shaft 92 with the oohtinuously rotating shaft 91, thus causing the fingers 57 58 of the fork 56 to be rotated'by at raising of the rod 67 (Fig. 7) by the com 98 to grasp a bundle of grain between their overturned ends 62,63. By reason of the unequal length of the fingore 57, 58, the bundle of grain will be par' tially turned from end to end when grasped by the fingers. The fork 56 is then swung horizontally-through an angle, whereby the turning of the bundle of grain from end to end is completed, and the bundle is brought to a position over the cradle 30 by a turning of the post 59, effected by the cam 97. A. counter-rotation of the fingers 57, 58, of the fork 56, efiected by the cam' 98, then releases the bundle of grain from the fork, per mitting it to fall into the cradle. A further movement of the cam 97 returns the fork 56' to a position adjacent the binder mechanism 28 for. grasping'the next bundle of greir'i formed therein.

;When the tubular shaft 92 has made one 95 c'iuplete revolution its movement is arrested by a raising of the pin 121, efiectecl by the contact of the head of thepin with the cam slide 129, and during such revolution of the tubular shaft the shaft 172 and cum disk- 167 (Fig. 6) are turned through .1 partial revolution by a swinging of the pawl urm 175 because of the turning of the eccentric 178 with the tubular shaft.

When a bundle of grain is removed from the binder mechanism 28 by the fork 56 and the fingers 150 thereby released, the operative parts of the binder mechanism, including the shaft 124, are brought to rest by a withdrawal of the movuble member of the 9 clutch 1 19 from contact with the clutch face of the sprocket 127by iheuns of the spring 162. At; the cum their 167 is turned through only a. port of u revolution ouch time"u bundle oi groin is delivercd'to the cradle 30 by the fork 56, a plurality of bundles will be permitted to accumulate in thecredle be-' fore the notch 168, rcvided in the periphery of the com disk, comes in front of the com roller 170 to release the crank-shaft 163.

During the tilting ofthe cradle obout the arm 31, the descending loud contained therein Will react upon the arm because of its'ten'de'ucy to full in it straight line, and a yie1dihg of the flexible p0rtionsa180, 181, of the brczce rod 172 will permit the arm to be I swung; forwardly thereby about its pivotal support 32. The cradle will thus be permitted to remain stationary for the settling of its load upon the ground until the brace rod 175) is again drawn taut by the forward movement of the machine.

The tapered form of the cradle 30, to gether with the inclined relation of the shafts 4-8 carrying the arms 46, .47, for comdlcs to be tied together with twine, or otherwise secured to each other.

Preferably the arms 57, 58, of the fork 56 are inclined toward each other, as shown in Fig. 1, and they are united near their free ends, as by a strap'ldi. As shown, the free end of this fork when at rest occupies a position somewhat to the. right of the binder mechanism 28, as viewed in Fig. 1 of the drawings, and in operation is moved first to theleft by the cam 97 to engage a bundle of grain, and then to the right to discharge the bundle of grain in the cradle 30.
